In my very lengthy story in the near future, there are some great 'Modern Marvels'. The next one I'm going to introduce might not be feasible, but if it is, I'd like to attach some numbers to it. ...
As you might know, our Universe is expanding. In fact, the expansion is accelerating (due to dark energy). As expansion progresses, patches of the universe will not be visible anymore (they cross t...
Assuming we have a world at the same stage in global warming as the Earth, with all other properties similar (population, carbon emissions, general climate, orbit, etc.) How long will it be until t...
If a human were cursed with the need to transform into a specific animal (i.e. a canine), would his DNA change after the transformation? I would appreciate help in answering this question. This i...
Scenario: Last line of defense. I want to prevent anyone from reaching a highly guarded building. Such building is in the middle of top secret, heavily guarded military area (think of Area 51). I ...
I am super-rich person with a net worth of 32 billion US dollars. Part of my business is being contractor for NASA and SpaceX (so I have knowledge about space technology). I already own my island ...
Diamonds are carbon. Plants take in CO2 and use the carbon. Chemically, could the right kind of plant have diamonds for berries, or is there some other limiting factor?
I was looking a bit at the evolution of Stars and one thing I sometimes see floated is this idea that in the far flung future, when the sun has ballooned into a red giant and the earth burned to a ...
For the sake of the question, assume conditions are Earth-like in all manners other than those which would be required to spur the development of such a plant. I want the plant to gestate in the di...
Could primitive human like species evolve into highly advanced race only using bio materials (other than wood) during their advancement (instead of other tools as early humans developed from iron, ...
I'm planning to incarcerate a supervillain who has the ability to attract and control metal. As a minimum, I'd quite like to light his cell but obviously putting even small amounts of metal into hi...
Currently I am working on how to explain a character that can "phase" through objects in a similar manner to Martian ManHunter. His abilities are negated by certain (rare) metals. His ability cou...
Carbon dominates the makeup of life on Earth. But is there any way that plants could be made out of metals, or somehow integrate metals with their constitution? For example, we use calcium in our...
In most star systems, planets orbit around a star. Is it possible for a planet to be so massive/heavy/dense that a star(and other planets) orbit it instead? Bonus points if the planet is also reaso...
I was trying to create a world that has extensive massive rain-forests unlike anything on earth where the trees interlock with thick branches to allow them to rise much higher into the air (several...
Namely, a creature that is immobile and stone(like) during the day and mobile at night. Something like the old cartoon, but they don't have to be sentient. They don't have to be actual stone, jus...
How do I define the Classical Elements with Science so that it agrees with science? According to a single property of a substance. So, no Fire = Energy, Water = Liquid, Earth = Solid, Air = Gas.....
The title of this question is fairly self-explanatory. I am developing a fantasy world, and I want to know what factors determine what kinds of trees I can have, where I can put them, and why. I ...
Could a species of aquatic mammals develop bio-luminescence? What kind of bio-luminescence would it be? What circumstances could lead to it?
Epic fantasies typically depict northern areas as cold and southern areas as relatively warm. Is this just to play into reader expectations since that's the way it is on Earth, or is there a scient...
Here is the setup: Elves, through magic, have the ability to cause regeneration of limbs/healing of wounds through natural cellular processes. Regenerating a limb, while now possible, obviously tak...
On today's Earth, a mysterious cube of no light has appeared, about the size of a house. It's confounding, because it appears to have the mass of stone, by the way it is difficult to move and the ...
Similar, but a bit more broad, to Would a zombie apocalypse be possible if a zombie existed? A secret lab (owned by a private company) near Chicago creates a virus strain called 'ZB01' (to be so...
In the future a major problem arose: a habit spread among the astronauts to make political statements upon landing on a new celestial body, often the statements were unpleasant to their government....
